This study investigated the feasibility of energy conversion and aluminum recycling on Tetra Pak and non-recycled plastic films containing aluminum in gasification by controlling a gasification temperature between 600℃~900℃and a equivalent ratio (ER) between 0.1~0.3. The results indicated that the energy conversion efficiency enhanced with an increase in gasification temperature. In the case of gasification temperature 900℃ and ER 0.3, the heating value of synthesis gas was approximately 10.73 MJ/Nm3, whereas the maximum hydrogen production was 26.87% in synthesis gas. Based on the results of energy density, the heating value of synthesis gas produced from Tetra Pak and non-recycled plastic films containing aluminum were approximately enhanced 3.67 folds and 8.8 folds of energy output in comparison with the original tested materials, respectively. According to the results of feasibility of aluminum recycling from gasified residues, the precursor of aluminum oxide only formed on the surface of tested materials. The major speciation of residues was aluminum identified by X-ray diffraction (XRD). The estimated amounts of aluminum recycled from per ton of Tetra Pak and non-recycled plastic filmswere 49 kilograms and 288 kilograms, respectively. It has a potential for applying the aluminum recycling and recovery in the future. In summary, the results of this research could provide important information for the selection and application of technologies in energy conversion and aluminum recovery from Tetra Pak and non-recycled plastic film containing aluminum.
